ACR300 Bus Validator

ACR300 Bus Validator


ACR301-B1 is a bus validator designed specifically for Automatic Fare Collection (AFC) systems for public transport. It is an improved version of ACR300, with newly added WiFi and GPRS capabilities.

The ACR301-B1 Bus Validator supports all ISO14443 Type A & B and Mifare smart cards. Through the embedded 32bit ARM 9 processor, ACR301-B1 Bus Validator can complete typical transaction within 0.2 seconds after presentation of the card, including recovery and backup. A special anti-collision algorithm effectively prevents the collision conflict when the user has many contactless cards put together, e.g. in his purse. A special anti-tearing mechanism also guarantees the transaction to be either completed or rejected, avoiding any data corruption and unexpected transaction error.

There are two card slots for holding Purchase SAM cards to ensure the security and integrity of transactions. Furthermore, the data storage in ACR301-B1 Bus Validator is tailor-made for AFC applications, and the memory capacity is more than enough for storing whole-day transaction records and blacklists.

Equipped with GPS, ACR301-B1 enables you to locate vehicles and set corresponding fares flexibly, with reference to distance. ACR301-B1 Bus Validator has integrated smart card readers, bigger display and white backlight  (to show bigger words with better contrast), audio, LED indicators and reliable waterproof casing, making it perfect for various types of automatic fare collection systems, e.g. for buses, ships, trams etc.
